Data corruption is the unintended change of a file or the loss of information which usually occurs during reading or writing. The reason can be hardware or software fail, and due to this fact, a file may become partially or entirely corrupted, so it'll no longer work as it should because its bits shall be scrambled or lacking. An image file, for instance, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When such a problem appears and it isn't identified by the system or by an admin, the data will become corrupted silently and when this happens on a disk drive that's part of a RAID array where the data is synchronized between various drives, the corrupted file will be copied on all of the other drives and the harm will be long term. A number of commonly used file systems either don't feature real-time checks or don't have good ones which can detect a problem before the damage is done, so silent data corruption is a very common problem on hosting servers where large volumes of information are kept.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the data uploaded in every single shared hosting account which is generated on our cloud platform as we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption through a unique checksum for every single file. We will store your information on a number of NVMe drives which operate in a RAID, so the exact same files will be present on several places at the same time. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file differs from what it should be, the file system swaps that file with a healthy copy from a different drive in the RAID. No other file system uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives with time, but since that can never happen on a server running ZFS, you won't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not have to deal with any kind of silent data corruption issues whatsoever in case you get one of our semi-dedicated server plans as the ZFS file system that we employ on our cloud hosting platform uses checksums to make sure that all files are intact all of the time. A checksum is a unique digital fingerprint that is allotted to each and every file kept on a server. As we store all content on multiple drives at the same time, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any chance of the damaged copy to be synchronized on the other hard disks. ZFS is the sole file system out there which uses checksums, which makes it much more reliable than other file systems which are not able to identify silent data corruption and copy bad files across hard drives.
